Overview

Immediate defibrillation is the main intervention for pVT.

Defibrillation

• As opposed to other unstable Ventricular tachycardia, PVT should be managed with immediate defibrillation. A high energy defibrillator (150-200 J on biphasic and 360 J on monophasic) should be used for the initial shock dose, followed by an equal or higher shock dose for successive shocks
• 5 CPR cycles each containing 30 chest compressions and 2 breaths should be done after the first shock is delivered. Each subsequent shock should be followed by airway management with Oxygen delivery, and IV access with vasopressors.

No

Shock

CPR 2 min Amiodarone or Lidocaine Treat reversible causes

Box D: CPR 2 min Treat reversible causes

Go back to box A

No

Rhythm shockable?

Yes

Shock Then, go to box A or box B

If no signs of return of spontaneous circulation: Go to box C or box D If return of spontaneous circulation: Start post cardiac arrest care
